Stabilization of body-care and household products

Abstract

A description is given of the use of light stabilizers of formulae (1) and/or (2) for protecting body-care and household products from photolytic degradation.

1. A method for protecting body-care and household products wherein said body-care and household products are stored in a container, said container has a low absorption in the UV-A range and said body-care and household products are subject to photolytic degradation from UV light which comprises incorporating into said body care or household products from 50 to 1000 ppm of a benzotriazole of formula 
       
         
           
           
               
               
           
         
       
       and optionally from 50 to 1000 ppm of a triazine compound of formula 
       
         
           
           
               
               
           
         
       
       wherein
 L 1  is C 1 -C 22 alkyl, C 2 -C 22 alkenyl or C 5 -C 7 cycloalkyl; 
 L 2  and L 6  are each independently of the other H, OH, halogen, C 1 -C 22 alkyl, halomethyl; 
 L 3 , L 5  and L 7  are each independently of one another H, OH, OL 1 , halogen, C 1 -C 22 alkyl, halomethyl; 
 L 4  is H, OH, OL 1 , halogen, C 1 -C 22 alkyl, phenyl, halomethyl; 
 L 12  is C 1 -C 22 alkyl, phenyl C 1 -C 5 alkyl, C 5 -C 7 cycloalkyl, OL 1  or a group of formula 
 
       
         
           
           
               
               
           
         
         j is 0, 1, 2 or 3 
         wherein said benzotriazole of formula (3) is completely dissolved in said body-care and said household products; and wherein said body-care and said household products comprise a pH range from 5.6 to 5.75 or a pH range from 6.0 to 6.5. 
       
     
     
       2. The method according to  claim 1 , wherein said body care or household product further contains a fragrance or odoriferous substance.
